JWT-Based Security
Implement token-based authentication using JSON Web Tokens (JWT) for stateless APIs.
Intro to JWT-Based Security
Welcome to the final lesson on Spring Security! Today, we'll explore JSON Web Tokens (JWTs), a popular method for securing stateless APIs.
Unlike traditional session-based authentication, JWTs allow the server to remain stateless, making them ideal for microservices and mobile applications.
What is a JWT?
A JWT is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object.
- Compact: Small size, can be sent through URL, POST parameter, or inside an HTTP header.
- Self-contained: Contains all necessary information about the user, avoiding database lookups for every request.
